As well as providing impartial advice about nutrition and promoting a healthy diet, dietitians offer advice on food-related problems and are involved in the diagnosis and dietary treatment of disease.


Registered dietitians work with both healthy and sick people and are qualified to assess, diagnose and treat dietary problems at both an individual and population level. They often work with patients who receive their food by tube, and play a key role in medical teams to treat conditions such as diabetes, kidney failure, inflammatory bowel disease, food allergies and intolerances, eating disorders and malnutrition.

Dietitians mainly work in the NHS or private medical clinics, but may also work in other organisations.

Typical starting salary: £21,909 to £28,462 (Band 5 of NHS pay scale)
Average UK salary range £16,640 - £41,080

Nutritionists provide information and advice about food, diet and health, usually relating to people who are well. Registered nutritionists are experts in nutritional science and apply this in a variety of settings, including working with individuals, groups and communities.

Nutritionists mostly work in non-clinical settings such as food industry, research, teaching, sports and exercise nutrition, government and non-government organisations (NGOs). Some work within NHS public health departments or freelance as consultants (e.g. within the media).
